Journeyman plumbers are licensed by states and, in some places, by cities or counties, and each sets its own exam. We simulate two written exams whose formats the owners publish: the Texas board’s exam and ICC’s national G25 exam. One journeyman plumber pass covers both mocks and every drill.

Common questions
How many questions are on the Texas journeyman plumber exam?
The written portion has 100 multiple-choice items with a 120-minute limit at a Pearson VUE test center. Candidates who are not current tradesman plumber-limited licensees also take a hands-on practical: 6 items in 240 minutes at the TSBPE center in Austin or Waco.
What score do you need to pass the Texas journeyman plumber exam?
70%. If your exam includes the practical, you do not have an overall pass until both the written and the practical portions are passed, and the practical must be passed within one year of passing the written.
Which plumbing code is the Texas exam based on?
TSBPE tells candidates to study the Plumbing License Law, the Board Rules and either the 2018 International Plumbing Code with the 2018 International Fuel Gas Code or the 2018 Uniform Plumbing Code. It says the exam is not specific to either code, so you study one. In August 2026 the Board proposed moving its adopted codes to the 2021 editions.
Is the Texas journeyman plumber exam open book?
No. The candidate handbook says books, papers and other reference materials are not permitted in the examination room. The ICC G25 journeyman plumber exam is open book.
How much does the Texas journeyman plumber exam cost?
A $40 application fee to TSBPE, $68.50 for the written exam and $40 for the practical, then a $40 initial license fee after you pass both portions.
How many times can you retake it?
Pearson VUE allows up to five attempts at the written exam on one authorization, all within one year of your TSBPE authorization. You wait 30 days after a first failure, 60 days after a second and 90 days after each later failure.
What is the ICC G25 journeyman plumber exam?
ICC’s National Standard Journeyman Plumber exam: 70 multiple-choice questions, open book on the 2018 International Plumbing Code, 4 hours, $120 at Pearson VUE. ICC says licensing agencies may use its results to meet their testing requirement; check which exam your jurisdiction accepts. ICC says most trades exams need 70% to pass.
Does this practice test include the Texas practical?
No. The practical is hands-on: cutting and joining PVC, copper, threaded steel and no-hub cast iron, finding violations on real water heater installations, and building a scale two-story drainage and vent system. Questions cannot simulate that. Our questions cover the written portion and the code knowledge behind the practical.
Do these questions come from the TSBPE or ICC exams?
No. Every question is original practice written to TSBPE’s published review course and ICC’s G25 content outline, with our own explanation. TSBPE and Pearson VUE do not release exam questions.
